Answer:

a_{n} = 5n + 5

Step-by-step explanation:

The nth term of an arithmetic progression is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 10 and d = a₂ - a₁ = 15 - 10 = 5 , then

a_{n} = 10 + 5(n - 1) = 10 + 5n - 5 = 5n + 5

jackson is 54 miles from Lazy R resort. Ontario is 31 miles south of jackson. A land developer proposes building a shortcut road
AlexFokin [52]
Let A represents Jack's point, O represents Ontario and R represents the Lazy R resort. The figure showing the positions will be as in the figure shown:

The shortest distance will be found using the Pythagorean theorem:
c²=a²+b²
plugging the values you get:
c²=54²+31²
c²=3877 
c=62.266 miles

-4y=-2x+8 and 3x-6y=6 <br> Perpendicular, parallel, or neither?
DENIUS [597]

Answer:

The two lines are parallel

Step-by-step explanation:

  • Parallel lines have equal slopes and different y-intercepts
  • The product of the slopes of the perpendicular lines is -1 which means if the slope of one is m, then the slope of the other is -\frac{1}{m} (reciprocal m and change its sign)
  • The slope of the equation ax + by = c is m = \frac{-a}{b}
  • The slope of the equation by = ax + c is m = \frac{a}{b}

Let us use these rules to solve the question

∵ The 1st equation is -4y = -2x + b

∴ a = -2 and b = -4

∵ m = \frac{a}{b} in this form of the equation

∴ m = \frac{-2}{-4}

∴ m1 = \frac{1}{2}

∵ The 2nd equation is 3x - 6y = 6

∴ a = 3 and b = -6

∵ m = \frac{-a}{b} in this form of the equation

∴ m = \frac{-3}{-6}

∴ m2 = \frac{1}{2}

∵ m1 = m2

∴ The slopes of the two lines are equal

→ That means the two lines are parallel

∴ The two lines are parallel
